Mount Spurr eruption concerns are growing, and travelers headed to or from Alaska could soon feel the impact. Scientists from the Alaska Volcano Observatory have raised alarms about increased volcanic activity at Mount Spurr, a potentially explosive volcano in central Alaska. With the threat of eruption rising, officials warn that aviation and air travel disruptions may follow—possibly within weeks.
Located roughly 80 miles west of Anchorage, Mount Spurr has a history of explosive eruptions that have disrupted flights and blanketed parts of the state in ash. The observatory is now encouraging residents, tourists, and anyone considering travel to familiarize themselves with the risks associated with a potential eruption. The alert, shared on the platform X (formerly Twitter), outlines the importance of staying updated and being prepared for sudden changes in volcanic activity.
According to the observatory, one of the most immediate concerns is the threat of volcanic ash to aviation. Ash plumes from previous eruptions have risen tens of thousands of feet into the air—high enough to pose serious risks to aircraft engines. In 1992, Mount Spurr’s eruption led to the closure of Anchorage Airport for nearly an entire day. If similar activity occurs, air travel across Alaska and even trans-Pacific routes could be affected.
Is It Safe to Fly Over Alaska Right Now?
Travelers passing through Alaska’s largest airport or connecting to destinations across the state may face delays, reroutes, or cancellations should the volcano erupt. The timing and extent of these disruptions will depend on wind patterns, eruption strength, and overall weather conditions. Airlines, meteorological services, and emergency responders are closely monitoring the situation.
The observatory notes that aside from aviation concerns, ground-level risks remain relatively low due to the remote location of the volcano. The surrounding areas near Mount Spurr are largely uninhabited, reducing danger to people on the ground. However, those venturing into Alaska’s backcountry, including hikers, photographers, or adventure travelers, are being urged to stay clear of the area and heed all advisories from land and emergency managers.
Volcanic mudflows and pyroclastic flows—fast-moving clouds of hot gas, ash, and rock—are possible if an eruption occurs. While these are unlikely to reach populated areas, they could dramatically alter the terrain and cut off access routes in the vicinity.
Those with upcoming travel plans to or within Alaska are encouraged to follow updates from the Alaska Volcano Observatory and subscribe to the Volcano Notification Service. This will provide real-time alerts and safety guidance in case of volcanic activity that might affect flights or travel conditions.
Mount Spurr is no stranger to powerful eruptions. In 1953, a single eruption lasted about an hour but sent ash 30,000 feet into the air. The 1992 eruption involved three separate explosions over the summer months, with ash plumes reaching nearly 48,000 feet. Such historical data offers a glimpse into what could be expected if the volcano awakens again.
In light of the current alert, travelers should also check with their airlines for flexible rebooking policies and monitor Anchorage airport’s status if they’re flying into or through the area. Travel insurance that includes natural disaster coverage may also be a wise investment for those planning to visit the region soon.
Alaska remains one of the most breathtaking destinations on Earth, but its natural wonders come with occasional surprises. For now, Mount Spurr is quiet—but scientists stress that could change soon.
